Abstract

La présente invention concerne divers cathéters qui abordent les problèmes de recul potentiels. Un cathéter de ce type peut contenir de multiples lumières qui permettent l'évacuation de liquide de perfusion en divers points sur l'extrémité distale du cathéter. En outre, de multiples ouvertures peuvent être présentes sur l'extrémité distale du cathéter. Les ouvertures peuvent être recouvertes d'une membrane qui se rompt à une pression d'écoulement désignée. La pointe de cathéter peut contenir des trous borgnes qui restent recouverts, et sont uniquement ouverts pour devenir actifs lorsque cela est nécessaire. Lesdits cathéters peuvent comprendre de multiples sorties d'écoulement de liquide de perfusion, plutôt qu'un jet constant singulier sortant de l'extrémité distale du cathéter.
